Application tiled February 21,1903. Serial No. 144,545. (No model.)

To all whom, t may concern:

Bo it known that I, JOHN B. STANHOPE, a citizen of the United States,residing in the city and county of Philadelphia, in the State ofPennsylvania, have invented certainv new and useful Improvements inBarrel-Heading Machines, of which the following is a full,l

clear, and exact description, reference being had to the accompanyingdrawings,of which- Figure 1 is a, side elevation of` a barrelheadingmachine embodying my invention, the upper portion thereof being'brokenaway. Fig. 2 is aplan view of Fig. 1, parts being omitted. Fig. 3 is anenlarged section on line w, Fig. 2. Fig. et isa sectional side elevationof Fig. 3. Fig. 5 is an enlarged section on line y y, Fig. 2. Fig. 6isaside elevation of a modication. Fig. 7 is a plan view of Fig. 6. A

This invention relates to improvements in barrel-heading machines suchas` described in United States Letters Patent No. 545,388, issued to meAugust 27, 1895. Ihave shown in the drawings accompanying thisspecication such partsonly of that machine as are deemed suicient for anunderstandingof my present improvements. vThese comprise means forpreventing operation of the fhoopdriving mechanism when the pivotedhalves of the compression-ring are in the closed ppsition, butpermitting said mechanism Ato be operated when said halves are open,also improved means for locking the half-ringsin the closed position,all as hereinafter particulrarly described. y

Reference being had to the accompanying drawings, 1 denotes the mainframe of the machine52, the top plate thereof,which has a circularopening 3 to receive the barrel. 4 is an annular head below said topplate and registeringwith the opening therein andhaving aninwardly-projecting flange 5 at the top for supporting the hoop to bedriven onto the barrel. This head has a boss 6, throu gh which passes arod 7, and there area similar boss and rod on the opposite side of thehead, these bosses being adapted to slide vertically on the rods 7. 8(marked 44 in said patent) is the circular table (indicated by dottedlines in Fig. l) for supporting the head to be inserted vin the barrelbefore the hoop is driven on.

it is adapted to be moved vertically by means of a hand-lever 9 upon arock-shaft lO, that has a lever connection 4with said standard.

1.1 denotes the spreader-arms for spreading the barrel-staves, so as topermit the head of the barrel to come into proper position within theend of the barrel. The lower ends of these spreaders arepivoted to apart of the frame ofthe 1nachine,and they are adapted to be movedinwardly and outwardly-that is, radially-by a foot-lever 12, that has oonnecs tion with a head 13,`Wl'1ich is adapted to slide upon theaforesaid standard that carries the table 8, and which head is connectedwith the spreader-arms 1l by pivoted rods V14..

The bosses 6 of head 4 are connected with the frame of the machine bytoggles 15, one of which isrshown in the drawings.' A rod 16 isconnected to the toggles. In the machine of my said patent the saidtoggles are operated by 'manual power and the rod 16 is connected. to ahand-lever. In my present invention I prefer to use steam or compressedair as the motive power and connect the rod lwith one arm of abell-crank lever 17'on a shaft 18. The other arm of said lever isconnected with the piston-rod 19 of a compressedair-engine cylinder 2O.vy

2l is a rod for operating a valve Within a box 22, into which enters apipe 23, leading from a source of supply of compressed air. Thevalve-rod 21 is operated byha'nd to allow the air to enter from thevalve-box into the piston-cylinder upon either side of the piston, as'may be required. In the position of the parts shown in the drawings thepiston is at the limit of its upward stroke, at which time the head i isat its lowest position.

24 indicates the l1alfrings, each of which' 4has an arm 25, that ispivoted onthe plate 2.

The general construction and operationof the machine does'not materiallydiffer from that of my said patent; but before proceeding to describe myimprovements VI shall briefly describe the mode of .operation of lthemachine. The part-s beingin the position shown in the drawings, whichcorrespond with the position shown in Figs. 2 and 9 on said pat Ima ent,in which the end of the barrel is resting upon the spreader-arms and thehalf-rings are closed against the barrel and the head to be inserted inthe barrel lies upon the table S (4c/1l in the patent) and the hoop tobe driven rests upon the flange 5 of the head 4, the spreader-arms 1lare now expanded by the attendant pressing down the foot-lever l2,thereby spreading the barrel-staves. At about the same time thehand-lever 9 is actuated to cause the table 8 to ascend and bring thebarrel-head thereon opposite to the usual groove on the inner side ofthe barrel. The half-rings are now opened, and the head l, upon whoseflange 5 the hoop is supported, is then forced upwardly by theapplication of power to the toggles l5, and thus drives the hoop ontothe barrel. The half-rings must be opened out before actuation of head4; otherwise the end of the ange would, before the head reaches thelimit of its upward movement, strike against the half-rings. Inoperating the machine shown in my said patent without my improvementshereinafter described it sometimes occurred that the attendant neglectedto open thehalf-rings before actuating the head 4E in driving on thehoop. ln order to prevent liability of such accident, I employ meanswhereby the power cannot be applied to operate head 4 when the halfringsare in the closed position-that is, whereby the act of closing thehalf-rings prevents the application of such power and the openingthereof permits such application.

' Ihcso means are as follows: I provide the arm 25 of one of thehalf-rings with an extension 2G beyond its pivot, that is adapted whenthe half-ring is closed and the valverod 2l is in the elevated positionto engage under a head or enlargement 27, which I provide on saidvalve-rod, thus preventing the latter from being pressed down to allowthe air to pass into the upper part of the enginecylinder to actuate thetoggle to force up the head. Although not essential, I usually make thefree end of the extension forked, as shown, the ends of the forks 28passing beyond the valve-rod. \Vhen the said half-ringis opened out, theend of the extension 26 will be disengaged i'rom the enlargement 27. Isometimes also provide the arm of the other half ring with a similarextension 26, as seen in Figs. t5 and 7, and the valve-rod 2l with asecond enlargement 29, under which said extension is adapted to passwhen thc half-ring is closed. As, however, it is customary for theattendant to throw open both half-rings simultaneously, and sometimesthey are adapted to be opened automatically by means of weights suitablyconnected therewith, I usually provide only one of the arms with anextension. When a hand-lever or other de-l vice for actuating the head 4is employed, it may be locked against operation by the closing of thehalf-rings.

In the machine as heretofore constructed the half-rings were locked inthe closed position by a hand-lever pivoted upon a lug of one of thehalf-rings and adapted to be swung into and out of engagement with a lugon the other half-ring, as described in my said patent. I now provide ameans whereby these half-rings are automatically locked in the y closedposition and released at the proper time. rFhese means are as follows: Imake a hole 30 in each of two lugs 3l, that project laterally from therespective half-rings, and also holes 32 through the plate 2,thatsupports the half-rings, the holes of the latter registering with thoseof said lugs. The holes 32 serve as guides for pins 33, which are in thepresent instance the prongs of a fork that is pivotally connected to arod 34:, which is pivoted to the foot-lever 12. When the latter ispressed down, the pins 33 will be carried below the lugs 3l, and thehalf-rings may then be brought into the closed position, and when thelever returns to the elevated position said pins will pass up throughthe holes in said lugs, and thus lock the half-rings in the closedposition. For convenience in closing and opening the half-rings Iprovide each of the same with vertical studs 35. When but one of thehalf-rings is provided with means for preventing the application ofpower to force up the head 4, as hereinbefore described, I sometimes, inorder to insure the opening of the other halfringr before the said headcan reach the same, provide the head with an upn wardly-extending wedge3G, that is adapted to impinge against the inner side of the arm 25 ofsaid other half-ring and open the same before the head shall have movedup to the full extent.

Having thus described my invention, I claim as new and desire tosecureby Letters Patentl. In a machine of the character described, thecombination of the head for holding and driving the hoop, means foractuating the same, the pivoted half-rings and means car ried by saidhalf-rings for automatically pre venting the operation of said actuatingmechn anisni when said half-rings are in the closed position,substantially as described.

In a machine of the character described, the combination of the headfor holding and driving the hoop, the engine for actuating the same, therod for operating the valve of said engine, the pivoted half-rings, andthe arms adapted to engage said rod and prevent the same from beingoperated when said halfrings are in the closed position, substantiallyas and for the purpose described.

In a machine of the character described, the combination of the head forsupporting and driving the hoop, means for actuating said head, thepivoted half-rings, means car ried by one of the latter forautomaticallypreventing the operation of said actuating means, when saidlast-mentioned half-ring is in the closed position, and the wedgecarried by said head, and adapted to impinge against said otherhalf-ring when in the closed position IUD IIO

and to open the same when the head is moved upwardly, substantially asand for the purpose described.
